[PATCH] Remove stale d_splice_alias comment

From: Oleg Drokin
Date: Mon Jun 20 2016 - 12:12:10 EST


It's not really possible to call d_splice_alias with a hashed
dentry no matter what, so remove the stale comment indicating
otherwise. The only user of this functionality was fixed
long ago according to Al.
